“…32 Other studies have investigated the regional thickness of the skull bones in relation to bone graft harvesting. [19][20][21][22]40 It is again difficult to compare these data with our findings, as most of these studies report on averages of measurements in selected points. However, in general, our data compares well to the data reported, although our thickness data are slightly larger.…”

laboratory investigation J neurosurg Pediatr 16:687-702, 2015 F inite element models (FEMs) of the human head are widely used for studying the biomechanics of traumatic brain injury. 12 FEMs of the human head are virtual computer models representing a human head in great anatomical detail. These models try to offer a better understanding of brain injury tolerance by simulating stress and strain patterns in the skull and brain tissue after impact, mimicking the occurrence of traumatic brain injury as realistically as currently possible. These models try to accurately predict the circumstances that cause traumatic brain injury. To do this, an FEM needs material properties of the brain tissue and skull to correlate a particular applied inertial and contact load to resulting intracranial strains and stresses. Therefore, a correct anatomical representation and use of correct material properties of a child's skull and each intracranial tissue are necessary to develop an FEM of a child's head, capable of realistically simulating the response upon impact. Only such an obJect Finite element models (FEMs) of the head are used to study the biomechanics of traumatic brain injury and depend heavily on the use of accurate material properties and head geometry. Any FEM aimed at investigating traumatic head injury in children should therefore use age-specific dimensions of the head, as well as age-specific material properties of the different tissues. In this study, the authors built a database of age-corrected skull geometry, skull thickness, and bone density of the developing skull to aid in the development of an age-specific FEM of a child's head. Such a database, containing age-corrected normative skull geometry data, can also be used for preoperative surgical planning and postoperative long-term follow-up of craniosynostosis surgery results. methods Computed tomography data were processed for 187 patients (age range 0-20 years old). A 3D surface model was calculated from segmented skull surfaces. Skull models, reference points, and sutures were processed into a MATLAB-supported database. This process included automatic calculation of 2D measurements as well as 3D measurements: length of the coronal suture, length of the lambdoid suture, and the 3D anterior-posterior length, defined as the sum of the metopic and sagittal suture. Skull thickness and skull bone density calculations were included. results Cephalic length, cephalic width, intercoronal distance, lateral orbital distance, intertemporal distance, and 3D measurements were obtained, confirming the well-established general growth pattern of the skull. Skull thickness increases rapidly in the first year of life, slowing down during the second year of life, while skull density increases with a fast but steady pace during the first 3 years of life. Both skull thickness and density continue to increase up to adulthood. conclusions This is the first report of normative data on 2D and 3D measurements, skull bone thickness, and skull bone density for children aged 0-20 y...

M. Potential donor sites of the parietal for bone grafting and its relationship to the cephalic index. Int. J. Morphol., 35(3):986-991, 2017. SUMMARY:The purpose of the present study was to chart the thickness of the parietal bone and establish its relationship with the cephalic index and sex aiming at improving current knowledge and guidance for obtaining calvarial bone auto-graft material. Both left and right parietal bones of 150 skulls of adult human cadavers classified as either dolicho-, meso-, or brachicephalic, and as either male or female had their thickness measured at 3 levels -superior (S), middle (M) and inferior (I) -and at 3 points -anterior (a), middle (m) and posterior (p) -in each level, all evenly laid out. No relevant differences in thickness whether comparing sex or cephalic index was evidenced. The thickest measurements were found at points located at superior and middle levels in middle and posterior positioning -Sm, Sp, Mm and Mp -with median values ranging from about 5.5mm to 7.13mm. At inferior level and posterior positioning, thickness median values ranged from 4.71 to 5.84mm. Safer harvesting of bone graft material occurs in Sm, Sp, Mm and Mp areas of the parietal bone. Only exceptionally should Ip domain be used, whereas Sa, Ia and Im regions should be considered non-donor sites.

“…There are many discussions and controversies about the use of materials to bone grafting and reconstruction; both autologous bone and allogenic and alloplastic materials can be used. However, the best results have been reported with autogenous bone, for it has osteogenic and osteoinductive capacity, and does not trigger specific immune response, making it an ideal grafting material 1 . The choice of possible donor sites for bone reconstruction depends mainly on the bone volume required and the type of defect 2 .…”

Thus, bone grafts from intraoral or extraoral donor sites represent a very favorable opportunity. This study aimed to review the literature on the subject, seeking to discuss parameters for the indications, advantages and complications of techniques for autogenous bone grafts.
